Detection of Anomalous Gravitational Effects in High-Temperature Superconductors Under Inhomogeneous Magnetic Field Gradients and Pulsed Microwave Radiation

This document is the full technical companion to the minimum experiment proposal (Doc1). It proposes detection of anomalous gravitational effects in high-temperature superconductors under inhomogeneous magnetic field gradients and pulsed microwave radiation, testing the quadratic field dependence predicted by Di Hao, Hu & Yu (2024–2026). Where Doc1 tests for rotation-synchronized repulsion (binary yes/no signal), this proposal tests for a specific functional signature: quadratic scaling of anomalous force with magnetic field gradient. Estimated cost: USD 5,250 (used equipment) to USD 14,100 (all new). Execution time: 8 months half time. Operating temperature: 77 K (liquid nitrogen). Target sensitivity: ~10⁻⁸ N. Key instrument: lock-in amplifier SR830. This document is part of a five-document series. Companion documents: minimum experiment (Doc1), plain language research summary (Doc3), historical analysis of the Tuck letter (Doc4), and convergence study Tuck-McDonald (Doc5) available in the same Zenodo repository. Version 4.0 (June 2026): Revised edition. Removed section arguing laboratory null results cannot rule out reactor-scale effects. Removed references to UAP-nuclear facility correlations, classified testimony, and speculative technology claims. Tajmar effect correctly qualified as internally significant but not independently replicated. The experimental design, budget, and timeline are unchanged.
